More great wifi access point ideas! From http://sirlagz.net/:
I recently got my Raspberry Pi to act as a WiFi Router with shaping by using hostapd, tc, and iptables together to broadcast as an Access Point, apply shaping rules, and apply packet marking respectively.
This can be done on any device with 2 NICs but this may come in useful for anyone using the Pi as a router but doesn’t want people using all the bandwidth.
I will be going through the iptables and tc configuration in this post, but I won’t go through the hostapd setup as that was the same as part 3 of my Raspi WiFi Access point guide.
I started off with a blank slate of Raspbian Server Edition again, and I didn’t need to install any utilities as iptables and tc are installed by default.
